I definitely second this suggestion, but I think it can be expanded a little as well. It would also be useful if there were a group finder category for the heroic Star Fortress FPs, though I imagine that would be somewhat more complicated to implement than simply allowing the solo versions to count for story progression. In a related vein of 'old content that needs updating to be feasible', Trouble in the Tion Hegemony is needlessly complicated to complete by virtue of the fact that veteran mode Kaon Under Siege and The Lost Island are not in the group finder. Thankfully, master mode is, but that's small consolation when your pug wipes eight times trying to kill Project Sav-Rak. Colicoid War Games is another FP not available through the group finder and quite impossible to solo. In my view, all of these need either some facilitation of assembling groups and/or changes to make them soloable.
